Tomas's suggestion definitely is the better if you're altering the
type of a single column. If you need to make more extensive changes
to the table structure, copying usually is the better way to go.

Hi,
(Postgres 9.5 and 9.6)
We have a table of about 650million rows. It's a partitioned table, with two
"child" tables. We want to change its primary key type from int to bigint while
retaining the current values.
We're using this:
ALTER TABLE dta.my_table ALTER column table_id TYPE bigint;
